Splitting (fracture) of a crystal on a crystallographic plane of' low index.

Electrochemical system consisting of an anode and a cathode immersed in an electrolyte. The anode and cathode may be separate metals or dissimilar areas on the same metal. The cell includes the external circuit, which permits the flow of electrons from th ...

In electroplating, a supplementary anode positioned so as to raise the current density on a certain area of the cathode and thus obtain better distribution of plating.

The maximum compressive stress a material is capable of developing. With a brittle material that fails in compression by fracturing, the compressive strength has a definite value. In the case of ductile, malleable, or semiviscous materials (which do not f ...

A decrease in the polarization of an electrode; the elimination or reduction of polarization by physical or chemical means; depolarization results in increased corrosion.

An anode that is insoluble in the electrolyte under the conditions prevailing in the electrolysis.

A positively charged ion that migrates through the electrolyte toward the cathode under the influence of a potential gradient. See also anion and ion.

The mass of unit volume of a material at a specified temperature.

Ability of a metal to withstand corrosion in a given corrosion system.

A compound with a central atom or ion bound to a group of ions or molecules surrounding it. Also called coordination complex. See also chelate, complexation, and ligand.

Foreign substance which comes from the environment, adhering to a surface of a material

The process in which a metal fractures prematurely under conditions of simultaneous corrosion and repeated cyclic loading at lower stress levels or fewer cycles than would be required in the absence of the corrosive environment.

The liquid material remaining from pulpwood cooking in the soda or sulfate paper-making process.

A composite metal containing, two or more layers that have been bonded together. The bonding may have been accomplished by co-rolling, co-extrusion, welding, diffusion bonding, casting, heavy chemical deposition, heavy electroplating, or explosive claddin ...

(Galvanic Corrosion) Corrosion resulting from dissimilar metal contact.

The number of cycles of stress that can be sustained prior to failure under a stated test condition.

The development of slight breaks in a coating that do not penetrate to the underlying surface.

A cell developed in an electrolyte resulting from electrical contact between two dissimilar metals. See galvanic corrosion.

The ratio of the electrochemical equivalent current density for a specific reaction to the total applied current density.

A pair of dissimilar conductors, commonly metals, in electrical contact. See also galvanic corrosion.
